Description
Die Erfindung betrifft eine Vorrichtung zum Filtern eines Rußpartikel transportierenden Abgases einer Maschine.The The invention relates to a device for filtering a soot particle transporting exhaust gas of a machine.
Allgemein bekannt sind Filtereinrichtungen aus porösen Materialien, wobei diese Filtereinrichtungen üblicherweise in einem Außenbehälter angeordnet sind. Als Material für die Filtereinrichtungen dient dabei im allgemeinen ein poröses Material, welches z. B. ein Sintermaterial aus metallischen Werkstoffen oder auch aus Glas oder Kunststoffen sein kann.Generally Filter devices made of porous materials are known, these being Filtering devices usually arranged in an outer container are. As material for the filter means is generally a porous material, which z. B. a sintered material of metallic materials or also made of glass or plastics.
Üblicherweise sind die Filtereinrichtungen, insbesondere wenn sie als Rußfilter für Abgasanlagen von Maschinen gedacht sind, aus hintereinanderliegenden Filterplatten aus dem oben genannten porösen Material in einem Außenbehälter aufgebaut.Usually are the filtering devices, especially when they are used as soot filters for exhaust systems are intended by machines, from successive filter plates from the above porous Material built in an outer container.
Beim Einsatz der Filtereinrichtungen als Rußfilter für die Abgase einer Maschine werden dabei häufig Filtereinrichtung und Schalldämpfer im Abgasstrang der Maschine zu einer Einheit zusammengefaßt.At the Use of the filter devices as soot filters for the exhaust gases of a machine become common Filter device and silencer in the exhaust line of the machine combined into one unit.
Das zu filternde Fluid muß bei diesem üblichen Aufbau der Filteranlagen eine oder mehrere Schichten aus dem porösen Material durchdringen, um eine ausreichende Reinigungswirkung zu erzielen. Dabei entstehen, durch die erforderlichen großen Oberflächen an porösem Material, vielschichtige Filter, welche dem strömenden Fluid einen sehr hohen Strömungswiderstand entgegenstellen.The to be filtered fluid must at this usual Structure of the filter systems one or more layers of the porous material penetrate to achieve a sufficient cleaning effect. This results in the required large surfaces of porous material, multilayer filters, which the flowing Fluid a very high flow resistance oppose.
Alternativen hierzu liegen darin, die Partikelfilter aus Metallgestricken oder aufgerauhtem Aluminiumoxyd-Garn herzustellen.alternatives These are the particulate filters made of metal or roughened alumina yarn manufacture.

Es ist Aufgabe der Erfindung, eine Vorrichtung zum Filtern eines Rußpartikel transportierenden Abgases einer Maschine zu schaffen, welches bei idealer Raumausnutzung in einem vorgegebenen Außenbehälter eine große Oberfläche an porösem Filtermaterial aufweist und das außerdem Schallwellen und Druckschwankungen in dem Abgas zu vermindern hilft.It It is the object of the invention to provide a device for filtering a soot particle transporting exhaust gas to create a machine, which is ideal Space utilization in a given outer container a large surface of porous filter material and that as well Sound waves and pressure fluctuations in the exhaust gas helps to reduce.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Die eigentliche Filtereinheit in dem Außenbehälter wird erfindungsgemäß dadurch gebildet, daß ein sich in Strömungsrichtung erstreckendes poröses Material entlang dieser Strömungsrichtung mehrfach gefaltet und mit den freien Enden zusammengefügt wird, so daß eine im Querschnitt geschlossene geometrische Form entsteht, welche wenigstens eine innere Öffnung aufweist. Das Material kann also z. B. in der Art eines vielzackigen Sterns gefaltet werden, so daß eine Art Rohr mit sternförmigen Querschnitt aus dem porösen Material entsteht.The actual filter unit in the outer container is formed according to the invention in that a porous material extending in the flow direction is folded several times along this flow direction and joined together with the free ends, so that a geo closed in cross-section metric shape is formed, which has at least one inner opening. The material can therefore z. B. be folded in the manner of a multi-pointed star, so that a kind of tube with a star-shaped cross-section of the porous material is formed.
Das zu filternde Abgas durchdringt diese sternartige Struktur dann von innen nach außen oder von außen nach innen, dadurch daß das Abgas entweder in das poröse Material eingeleitet wird und von dort in den Bereich des Außenbehälters einströmt oder daß das Fluid in den Außenbehälter eingelassen wird und aus der wenigstens einen inneren Öffnung des Querschnitts des porösen Materials abgezogen wird.The exhaust gas to be filtered then penetrates this star-like structure inside out or from the outside inside, that the Exhaust gas either in the porous Material is introduced and flows from there into the area of the outer container or that this Fluid is introduced into the outer container is and from the at least one inner opening of the cross section of the porous Material is deducted.
Durch die Faltungen ist man dabei in der Lage je nach Anzahl eine an die Erfordernisse bestmöglichst angepaßte bzw. größtmögliche Oberflächenquantität in dem üblicherweise in seinen geometrischen Abmessungen vorgegebenen Außenbehälter unterzubringen.By the folds one is capable of depending on the number one to the Requirements as best as possible adapted or largest possible surface quantity in the usual to accommodate specified in its geometric dimensions outer container.
Dadurch, daß lediglich die Anzahl und die Form der Faltungen verändert werden muß, kann aus einem endlosen Band des porösen Materials die jeweils erforderliche Filtereinrichtung hergestellt werden. Da diese üblicherweise mit numerisch gesteuerten Maschinen produziert wird, reicht es hier aus, für die jeweils erforderliche Filtereinrichtung ein leicht geändertes Steuerungsprogramm zu bevorraten, welches aus dem jeweils selben Material, ohne ein großes Umrüsten an der Maschine erforderlich zu machen, die an die jeweiligen Erfordernisse angepaßte Filtereinrichtung herstellen kann.Thereby, that only the number and shape of the convolutions must be changed from an endless volume of porous Material made the required filter device become. As these are usually is produced with numerically controlled machines, it is enough here out, for the each required filter device a slightly changed To stockpile control program, which from the same one Material, without a big one adapt required on the machine to meet the respective requirements adapted Can produce filter device.
Dabei dient der Außenbehälter mit der Filtereinrichtung neben der Filterung des mit Rußpartikeln behafteten Abgases gleichzeitig als Schalldämpfer. Dies bedeutet, daß durch die Einheit aus Außenbehälter und Filtereinrichtung gegebenenfalls vorliegende Druckwellen in den Abgasen vermindert werden, so daß keine störenden Geräusche an die Umgebung der Anlage gelangen können. Auch hierfür ist die große poröse Oberfläche annähernd ideal, da sie entsprechende akustische Effekte ermöglicht, welche es den Schallwellen in dem Abgas erlaubt sich "totzulaufen".there serves the outer container with the filter device in addition to the filtering of soot particles afflicted Exhaust gas simultaneously as a muffler. This means that through the unit of outer container and Filter device optionally present pressure waves in the Exhaust gases are reduced, so that no disturbing noises to the environment of the system can reach. Also for this is the big one porous surface nearly ideal, as it enables appropriate acoustic effects, which allows the sound waves in the exhaust gas to "run dead".
